I want to zoom the camera to look the picture . How to change the default zoom to focus on one area?
Unfortunately, CAM313 doesn't support autofocus/manual focus features. That said, you can only control the focal point under our recommended working distance: 40 cm - 100 cm (1.31 feet - 3.28 feet).
